Hand-wrote 51 cold outreach emails to higher ed in CO last week, would have sold a kidney for autocomplete in my own voice. then I see it's Mac only while I'm staring at my Windows taskbar. genuinely cruel. someone port this.
@david_mchale Sorry to hear that! If you visit https://cotypist.app from your Windows machine, you should have the option to sign up for a waitlist for a potential Windows version.
Since it operates globally across all text inputs, how does Cotypist handle low-level conflicts with native macOS auto-correct features or spelling engines in apps like Obsidian or Mail? Do you actively filter out system suggestions to prevent visual overlapping, or does the tab-completion mechanism override them? Congrats on shipping a very much needed product!
@konstant_gk Good question! Cotypist automatically offers to disable macOS' built-in inline text completions when you install it. I similarly recommend disabling built-in autocompletion features in e.g. Gmail and Google Docs; Cotypist's own suggestions should generally be more useful, anyway.

The system-wide angle is what actually makes this interesting - not just autocomplete in one app but everywhere you write. I keep context-switching between Slack, email, and docs all day and having suggestions that follow you across all of them without sending anything to the cloud is a real differentiator. Curious how it handles technical jargon and product-specific terms - does it adapt just from usage patterns or is there a way to seed it with your own vocabulary?
@galdayan Thanks for the question! Cotypist will use a screenshot of the app you’re typing in as well as the contents of the current text field. This already helps establish context, so that Cotypist's initial "educated guesses" are already pretty good. On top of that, you can also provide custom instructions (either generally or app-specific) to help Cotypist better adapt to the context; that is a good place to put jargon and product-specific terms in — but the models are often smart enough to already pick up on those just from the context. For example, the models have already "seen" enough medical and technical terminology that in such contexts the suggestions will often already be appropriate for that domain. And finally, Cotypist also learns from your typing over time, so that also helps it adapt to your writing style without you having to lift a finger!

Local-first is the right call for this category. The apps where autocomplete helps most are also where people write sensitive or unfinished material. The Mac-wide layer is the hard UX: suggestions useful enough to accept, quiet enough not to fight the writer.
@krekeltronics Indeed! In my experience, Cotypist's suggestions at this point are so often relevant that it's better to err on the side of showing them. But there's still the challenge of making sure that you never have to wait for completions to appear, which is why I’ve put a lot of effort into optimizing Cotypist’s performance.

How Cotypist handles different writing styles across work emails, Slack messages, and personal notes??
@ankur_jeswani Excellent question! Cotypist lets you provide custom instructions to generally tune it to your writing style. In addition, you also have the option to provide additional instructions for specific apps, to e.g. follow a more casual tone in Slack while keeping your emails more formal. Plus, Cotypist is also generally quick to pick up on the style of the current conversation, and will also learn from your writing in each app over time.
@nuseir_yassin1 Cotypist lets you provide custom instructions to generally tune it to your writing style as a starting point. But it indeed also learns from your writing over time, and that's where the real magic happens, to the point where it feels like a best friend completing your sentences — or as if it were reading your mind 😉

Cotypist is great! It is even helping me to write this comment.
The way it is able to so often anticipate what I want to write next is amazing. While at the same time, quickly taking into account changes as I type too.
@dylanb Thank you for the endorsement! I've indeed put a lot of effort into making sure that completions update quickly as you type, so even if the initial suggestion isn’t quite right, typing just one or two more letters will often give you exactly the word you were looking for, so that Cotypist still saves you the effort of typing the second half of the word.

Does Cotypist learn from my writing over time, or is the behavior fixed after installation?

Excited to see how it evolves going forward.
